A method of digital-driving an organic light emitting display device includes analyzing a light emission pattern of the input image data and converting a third grayscale of the input image data into a first converted grayscale and a second converted grayscale based on an analysis result of the light emission pattern of the input image data.

A display device includes a display panel, a dither table memory device, a dithering processor, and a display panel driver. The display panel includes a plurality of pixels. Dither tables are stored in the dither table memory device. The dithering processor selects a target dither table corresponding to a grayscale level of input data from among the plurality of dither tables and performs a dithering operation on the input data using the target dither table to generate dither data. The display panel driver drives the display panel based on the generated dither data.

Display device with improved display quality

A display device and method of adjusting luminance of a logo region of an image displayed on the same are disclosed. In one aspect, the display device includes a display panel configured to display an image including a logo region and a display driving integrated circuit configured to detect a logo estimate region of the image and determine a logo surrounding region that surrounds the logo estimate region. The integrated circuit is further configured to analyze a histogram of the logo surrounding region so as to determine a background maximum luminance, determine a high-gray-scale maximum luminance of the logo estimate region based on the background maximum luminance and adjust a gamma curve of the logo estimate region.
